Fluorite, a captivating mineral renowned for its enchanting hues, unveils a mesmerizing secret under the radiant beam of ultraviolet (UV) light. This enigmatic phenomenon transcends the ordinary, revealing a breathtaking symphony of colors that illuminate the darkness and ignite the imagination.
Unlocking the Fluorescence of Fluorite
Invisible to the naked eye under ambient light, fluorite’s latent beauty is awakened when exposed to UV radiation. The mineral’s complex chemical composition, primarily composed of calcium fluoride (CaF2), harbors unique impurities, known as activator ions. These ions, such as europium (Eu) and samarium (Sm), act as energy traps, selectively absorbing UV photons and releasing their captured energy as visible light.
The absorption and re-emission process is influenced by various factors, including the type and concentration of activator ions present. Each impurity imparts its own characteristic hue, painting a diverse palette of colors on the fluorite canvas.
